Embed / Subset problem.

Hi,
When exporting a PDF I had left the embed fonts as the default - some were embed, some subset.
The resulting PDF was fine for me using Evince PDF viewer, but one font was garbled when the pdf was viewed in the web browser.
When I subsetted all the fonts, this was fixed.

 - I don't really know what "subset" is. - but whats going on here?

The garbled font was Spectral Bold (Spectral Regular displays fine) even though both these were in the embed column.

Why would that one font not work unless its subset, but all the other fonts not care either way?

Thanks for helping me understand.

Some fonts cannot be embedded (because the PDF format does not allow it), those fonts are converted to a font that can be embedded, and these are indicated as subset.

OK. Thanks for that info. Its useful to know.

That makes sense for Calistoga & Dejavu because they are locked as subset & cannot be moved.

The problem font (spectral regular) is not in the subset list & can be freely moved to either column.

Ultimately it doesn't really matter because moving it to subset fixes the issue, I'm only really asking to understand the issue.
Perhaps its an odd glitch with just "spectral regular" - to be honest I havent noticed this issue ever before.
